Abstract
A kind of fusion cast frog, including heart rail and wing rail, the heart rail is intersected by track I and track II to be formed, reinforcing plate I and reinforcing plate II are equipped with the acute angle that track I and track II intersect to form, reinforcing plate III and reinforcing plate IV are equipped with the obtuse angle that track I and track II intersect to form, the wing rail is symmetrically set in heart rail both sides, the reinforcing plate, heart rail and wing rail integral cast shaping.Relative to the prior art, the technique effect of the utility model is, heart rail, wing rail are cast an entirety, which has higher-strength and wearability, and service life is generally more than 2 times of assembled frog, its is firm in structure, overall performance is good, and fusion cast frog, which also has, to be laid with conveniently, easy to maintenance, through built-up welding after abrasion, the advantages that planing can be continuing with after repairing.
Description
Technical field
It the utility model is related to railroad track field, and in particular to a kind of fusion cast frog.
Background technology
It a rail branch is two or more track that railway frog, which is, wheel is crossed another stock by one rail
The equipment of rail, plays an important role on rail track, and current railway frog is usually knockdown, will be pitched by union piece
The heart and wing rail are bound up, since knockdown railway frog is tied by union piece, so service life is short, limitation
Road speed, travel safety are low, maintenance input is big, become the weak link of track.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of block cast formula railway frog.
The technical solution of the utility model is specially：
A kind of fusion cast frog, including heart rail and wing rail, the heart rail is intersected by track I and track II to be formed, track I and rail
Reinforcing plate I and reinforcing plate II are equipped with the acute angle that road II intersects to form, is equipped with and adds at the obtuse angle that track I and track II intersect to form
Strong plate III and reinforcing plate IV, the wing rail are symmetrically set in heart rail both sides, the reinforcing plate, heart rail and wing rail integral cast shaping.
Reinforcing plate III 5 and reinforcing plate IV 6 are symmetrical arranged, its length exceedes the cross section of heart rail.
Relative to the prior art, the technique effect of the utility model is that heart rail, wing rail are cast an entirety, the railway frog
With higher-strength and wearability, service life is generally more than 2 times of assembled frog, its is firm in structure, and overall performance is good, whole
Cast railway frog also have be laid with it is convenient, it is easy to maintenance, through built-up welding after abrasion, the advantages that planing can be continuing with after repairing.
Brief description of the drawings
Fig. 1 is the schematic front view of the utility model.
Fig. 2 is the vertical view schematic cross-sectional view of the utility model.
Embodiment
As shown in the figure, fusion cast frog, including heart rail and wing rail 7, it is characterised in that：The heart rail is by track I 1 and track II
2 intersect composition, and reinforcing plate I 3 and reinforcing plate II 4, track I 1 and track are equipped with the acute angle that track I 1 and track II 2 intersect to form
Reinforcing plate III 5 and reinforcing plate IV 6 are equipped with II 2 obtuse angles intersected to form, the wing rail 7 is symmetrically set in heart rail both sides, described to add
Strong plate, heart rail and wing rail integral cast shaping.
Reinforcing plate III 5 and reinforcing plate IV 6 are symmetrical arranged, its length exceedes the cross section of heart rail.
It is to be assembled into together by union piece in knockdown railway frog in the prior art, between heart rail and wing rail
Obtuse angle angle does not fill reinforcing plate, and the utility model has filling reinforcing plate in the gap between heart rail and wing rail,
And integral cast is molded, intensity is high, firm in structure, and overall performance is good, service life length.
Above-described is only the preferred embodiment of the utility model, it is noted that for those skilled in the art
For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as
The scope of protection of the utility model.
